By using the data on Table $1$ estimate the following parameters:

a$)$ required membrane area $A_m(m^2)$

b$)$ process path length $(L_{pp})$

c$)$ Number of stacks $(N_{\text{s}\text{t}\text{a}\text{c}\text{k}})$

d$)$ Total power needed $(kW)$

e$)$ Specific energy consumption per $m^2$ of product $(kW\frac{h}{m^3})$

f$)$ Specific energy consumption per kgNaOH$(kW\frac{h}{k}$gNaOH$)$
